Align text to right in button in Jetpack compose - android

I have button with text:
Button(
colors = ButtonDefaults.buttonColors(
backgroundColor = Color.Transparent,
contentColor = colors.primary,
),
elevation = null,
onClick = {},
border = BorderStroke(0.dp, Color.Transparent),
) {
Text(
text = stringResource(id = R.string.name),
fontSize = 12.sp,
textAlign = TextAlign.Right
)
}
Now text in button is centered. How can I move this text to right/end in this button. textAlign = TextAlign.Right not working.


You have to specify width for Button and Text.
Button(
colors = ButtonDefaults.buttonColors(
backgroundColor = Color.Transparent,
contentColor = colors.primary,
),
elevation = null,
onClick = {},
border = BorderStroke(0.dp, Color.Transparent),
modifier = Modifier.fillMaxWidth()
) {
Text(
text = stringResource(id = R.string.name),
fontSize = 12.sp,
textAlign = TextAlign.Right,
modifier = Modifier.fillMaxWidth(),
)
}
I have given full width for Button
modifier = Modifier.fillMaxWidth()
Also let your Text to occupy that parent width.
modifier = Modifier.fillMaxWidth()

Jetpack Compose - Cant wrap content textField

I am doing some things with Compose and i encountered this problem
I cant understand WHY my textfield width is to the end of the parent. I want to wrap the content dependening on the input lenght. I painted the background red on purpouse.
I cant hardcode a padding because if the lenght of the field is too much the text starts to go out sight
What i am doing wrong?
Row(Modifier.wrapContentSize()) {
ConstraintLayout(
Modifier
.wrapContentSize()
) {
val (text1, text2) = createRefs()
Text(
modifier = modifier
.wrapContentWidth()
.constrainAs(text1) {
end.linkTo(text2.start)
top.linkTo(parent.top)
bottom.linkTo(parent.bottom)
},
text = "$",
color = Color.White,
fontSize = sp_50,
fontFamily = FontFamily(
Font(R.font.mulish_bold)
),
textAlign = TextAlign.Center
)
TextField(
modifier = modifier
.wrapContentWidth()
.constrainAs(text2) {
top.linkTo(parent.top)
bottom.linkTo(parent.bottom)
start.linkTo(text1.end)
}.background(Color.Red),
visualTransformation = {
show = it.isNotEmpty()
val value =
if (it.isEmpty())
NUM_0
else it.text
val amountFormat: String = notFormatAmount(value).toStringThousandAmount()
TransformedText(
AnnotatedString(amountFormat.take(amountFormat.length)),
OffsetMapping.Identity
)
},
value = text,
onValueChange = {
text = it
if (onTextChange != null) {
onTextChange(
it.ifEmpty { NUM_0 }
)
}
},
colors = TextFieldDefaults.textFieldColors(
textColor = Color.White,
disabledTextColor = Color.Transparent,
focusedIndicatorColor = Color.Transparent,
unfocusedIndicatorColor = Color.Transparent,
disabledIndicatorColor = Color.Transparent,
cursorColor = Color.Transparent
),
textStyle = TextStyle(
color = Color.White,
fontFamily = FontFamily(

),
textAlign = TextAlign.Justify,
fontSize = sp_50
),
singleLine = true,
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.NumberPassword)
)
}
}

Modified code:
Row(Modifier.wrapContentSize()) {
ConstraintLayout(
Modifier
.wrapContentSize()
) {
val (text1, text2) = createRefs()
Text(
modifier = modifier
.wrapContentWidth()

Aligning the text of a TextField with its Trailing icon

I have an svg icon in my drawables folder from our designer, and I'm trying to figure out a way to align the trailing icon of the TextField with its text in a way that it will look the same on most devices. I'm trying to avoid fixed dp values but I can't find a built-in way to do this.
screen code:
var customAmountTxt by remember { mutableStateOf(TextFieldValue()) }
TextField(
value = customAmountTxt,
onValueChange = {
customAmountTxt = it
},
maxLines = 1,
singleLine = true,
leadingIcon = {
Icon(
painter = painterResource(id = R.drawable.ic_euro),
contentDescription = stringResource(
R.string.euro_icon_desc
),
modifier = Modifier.padding(
start = 16.dp,
end = 16.dp,
top = 12.dp,
bottom = 12.dp
)
)
},
keyboardOptions = KeyboardOptions(
keyboardType = KeyboardType.Number,
imeAction = ImeAction.Done
),
keyboardActions = KeyboardActions(onDone = {
focusManager.clearFocus()
keyboardController?.hide()
}),
shape = RoundedCornerShape(6.dp),
colors = TextFieldDefaults.textFieldColors(
backgroundColor = colorResource(id = R.color.white),
textColor = colorResource(id = R.color.black),
focusedIndicatorColor = colorResource(id = R.color.white),
unfocusedIndicatorColor = colorResource(id = R.color.white),
disabledIndicatorColor = colorResource(id = R.color.white),
cursorColor = colorResource(id = R.color.black)
),
textStyle = TextStyle(
color = Color.Black,
fontSize = 16.sp,
fontWeight = FontWeight.Normal,
textAlign = TextAlign.Start
),
modifier = Modifier
.height(50.dp)
.fillMaxWidth()
.shadow(8.dp, shape = RoundedCornerShape(6.dp))
)
current output:

Jetpack Compose: Center Icon or Trailing elements in a ListItem

I'm trying to center the icon and trailing elements vertically using a ListItem. I'm not sure if it is possible or I need to drop the ListItem and use a combination of column/row instead.
I'm using something like:
ListItem(
Modifier.clickable(onClick = onClick),
icon = {
Box(
modifier = Modifier.fillMaxHeight(), contentAlignment = ALignment.Center
) {
Text(
text = dateUtil.formatTime(item.startTime),
style = TextStyle(
color = SnyDarkBlue,
fontSize = 14.sp,
fontFamily = oswaldFamily,
fontWeight = FontWeight.Bold,
letterSpacing = (-0.25).sp,
),
)
}
},
thanks in advance!

You can center both the icon and text sections using a Column:
ListItem(
modifier = Modifier
.fillMaxWidth()
.requiredHeight(50.dp)
.background(color = Color.Gray),
icon = {
Column(
modifier = Modifier
.fillMaxHeight(), verticalArrangement = Arrangement.Center
) {
Text(
text = "06:00 PM"
)
}
},
text = {
Column(
modifier = Modifier
.fillMaxHeight(), verticalArrangement = Arrangement.Center
) {
Text("Your item text goes here")
}
},
)

How to display a value for a TextField with a fixed height

If I put down a specific value for height, then my value for the text field moves somewhere, I can't understand why.
But if I don't set the height values, then everything is displayed in order
Here is my code:
Row(
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier
.fillMaxWidth()
// .size(40.dp)
.background(color = LightGray20, shape = RoundedCornerShape(6.dp))
.padding(6.dp)
) {
TextField(
modifier = Modifier.width(80.dp),
// .height(28.dp),
value = product.quantity.toString(),
onValueChange = {
it.toDoubleOrNull()?.let { value -> quantityChangeHandler(product, value) }
},
textStyle = LocalTextStyle.current.copy(textAlign = TextAlign.End, fontSize = 16.sp),
maxLines = 1,
keyboardOptions = KeyboardOptions(
keyboardType = KeyboardType.Number,
imeAction = ImeAction.Done
),
keyboardActions = KeyboardActions(
onDone = { localFocusManager.clearFocus() }
),
shape = RoundedCornerShape(8.dp),
colors = TextFieldDefaults.textFieldColors(
focusedIndicatorColor = Color.Transparent,
unfocusedIndicatorColor = Color.Transparent,
disabledIndicatorColor = Color.Transparent,
),
)
Text(
text = description,
fontSize = 16.sp,
maxLines = 1,
modifier = Modifier.padding(start = 2.dp)
)
}
Here is the my design what i want to do:
Here what i find about paddings:

Icons getting disappears if the text is too long in Jetpack Compose

#Composable
fun TopAppBar(
name: String,
modifier: Modifier = Modifier
) {
Row(
modifier = modifier
.fillMaxWidth()
.padding(20.dp, 0.dp),
verticalAlignment = Alignment.CenterVertically,
horizontalArrangement = Arrangement.SpaceBetween
) {
Icon(
imageVector = Icons.Default.ArrowBack,
contentDescription = "Back",
tint = Color.Black,
modifier = Modifier.size(24.dp)
)
Text(
text = name,
overflow = TextOverflow.Ellipsis,
fontWeight = FontWeight.Bold,
fontSize = 20.sp,
maxLines = 1
)
Row {
Icon(
painter = painterResource(id = R.drawable.ic_bell),
contentDescription = null,
tint = Color.Black,
modifier = Modifier
.padding(8.dp, 8.dp)
.size(24.dp)
)
Icon(
painter = painterResource(id = R.drawable.ic_dotmenu),
contentDescription = null,
tint = Color.Black,
modifier = Modifier
.padding(8.dp, 8.dp)
.size(24.dp)
)
}
}
}

You have to set the weight and the fill to false:
Text(
modifier = Modifier.weight(weight = 1f, fill = false),
text = name,
overflow = TextOverflow.Ellipsis,
fontWeight = FontWeight.Bold,
fontSize = 20.sp,
maxLines = 1
)

You can add the weight modifier to the Text composable
Row(){
Icon()
Text(
text = ".....",
overflow = TextOverflow.Ellipsis,
fontWeight = FontWeight.Bold,
fontSize = 20.sp,
maxLines = 1,
modifier = Modifier.weight(1f)
)
//...
}
.
